Question

pbf: benefits and limitations
use the information below to answer the question.
direct metal laser sintering is not necessarily the best process to use for everything that is made of metal. it may be more cost - effective to make your piece in the traditional method.
benefits

• the prints are dense.
• its good to use for projects that require complex geometry.
• it is organic.

limitations

• the machine has a large unit and is very expensive.
• it has a small build bed. you may need to create the piece in two parts and combine it for post - processing.
• it requires a lot of post - processing, like operator hand - grinding off the support structure, removing the powder, etc.

why do some powder bed fusion (pbf) prints need to be created in two separate parts?
the metal will not cure with large prints.
the support structure has weight limitations.
the heat source requires borders around the prints.
the machines have a small build bed.

Explanation:

The limitations section mentions that the machine has a small build bed. This means that for larger prints that exceed the build bed size, the piece may need to be split into two parts and then combined later. The other options are not supported by the given information. The text does not mention issues with metal curing for large prints, weight limitations of support structures, or heat source border requirements.

Answer:

The machines have a small build bed.
